Watch until the scene where Jimmy,Sheen,Carl are in Jimmy's lab and are talking about making him dumb. Jimmy puts on the helmet and switchs the control box to "normol" but it shorts and a cause it to go the "drool monkey". After that the camera zooms out to the boys and the slider has went from drool monkey back to enistien. Later when they all do the loopy dance it goes back to drool monkey . this happens 3 more times in the scene. I think it is fuuny.
